Hi, i am 15 years old, i had unprotected sex with my boyfriend. He didnt cum inside me, but i know he pre-cumed in me. and i know theres chances that can get you pregnant. I dont know the exact date of my last period, but i have been having pregnancy symtoms. I took a test november 20th and it came back negative. i dont know how accurate that is because i dont know when my last period was? do you have any advice?
